Is there something technically wrong with these? I ask because I have never had that terrible experience with any other core type I needed so far...Last civil war event I used the first half to get a couple of good promethium, makraan and adamantium cores from vendor boxes besides a couple of nice cores (radioactive and x gene) that dropped while playing
Then I decided to gear my captain america and oh boy...throughout the rest of the event, not a single goof vibranium core, not from drops or the vendor...I am not even looking for a trifecta just the invulnerability and the 25 regen (a bifecta if that's a term) and I dont care what 3rd affix is but no
I dismissed it as bad rng and this event I've been doing black panther, another vibranium dude, not a single "bifecta" from drops or vendor boxes...so again I say may be bad rng and I started asking in social chat only to find people talking about how vibranium cores are their worst enemy and how they spent forever to get their vibranium core...etc
So is this really a coincidence, or is something seriously wrong with that core type and I should put its characters on hold till it's fixed?
